Another query from an old 8bitter,
How important is getting the C revision ROMs for my XL? The B version,
which I no doubt have in my dinosaur, has some pretty terrible bugs
I hear, and I have no idea how to get the C revision. Can anyone answer
my ignorant pleas?
Oh, by the way, this isn't Ernest C. Spieu, it's his roommate, who
will hopefully soon get his own account.

C BASIC. I don't know if you can still buy the Rev. C cartridge, but an easy solution would be to find a friend with a 130XE (which has Rev. C BASIC), save to disk (from DOS 2.5 menu option K) the BASIC cartridge ($A000-BFFF), then write an assembly language header to precede the file you just wrote. The assembly language header will have to disable the BASIC ROM on your XL, then load the disk BASIC into the underlying RAM, then reset RAMTOP to $A0, then clear the screen (by opening and closing device #0). Then, just do a JMP $A000 and your Rev. C BASIC from the disk will run on your XL. --Norman Lin (A.K.A. NARC)

I believe ANTIC and ANALOG have software fixes for the dreaded B bugs. I don't have them with me now, but I'll try to get them to you tomorrow. In the meantime, anyone who know's what I'm talking about should be able to provide the information to you. P.S. Is printing the small listing on here a copywrite infringement? If it is I can still give you the issue numbers... Genghis.

It would probably be wiser just to give the issue numbers. --NARC

The assembly > language header will Um... I think you'll have problems with that binary save from DOS 2.5. If 2.5 works anything like 2,0 in it's burst mode writes, then it will attempt to write the cartridge out in burst mode, and totally mess up the sector links, yielding an undeletable useless file. Best to either turn burst mode off (the pokes are in Mapping the Atari under FMS), or write a small basic program to dump the ROM space to a file. Something like... 10 OPEN #1,8,0,"D1:BASICC.OBJ" 20 PUT #1,255:PUT #1,255:REM $FFFF file header 30 PUT #1,0:PUT #1,160:REM $A000 start address 40 PUT #1,255:PUT #1,191:REM $BFFF end address 50 FOR ADDR=40960 TO 49151:PUT #1,PEEK(I):NEXT ADDR:REM body 60 END:REM close too --------------------- Tom Klok Vancouver BC Canada tom_klok@mindlink.UUCP | a344@mindlink.UUCP

[Stuff deleted...] No, I've tried it, and it works, and I read somewhere that they fixed that burst-mode stuff for DOS 2.5. I believe it copies it to a RAM buffer before writing the sector link information. Anyway, as I said, I tried it, and it works, so I think it's pretty safe. -- Norman Lin This is my humble signature file.

I don't know if you can still buy the >Rev. C cartridge, ... It may be simpler than that. I wrote a letter to Atari Customer Support to ask how I could get my Rev B Basic upgraded to Rev C, and the reply stated that I should send a copy of my receipt for purchase of the unit, and they would send me a Rev C cartridge. Since the receipt had been tossed, however, I was unable to comply. This was a few years ago; I don't know whether the offer is still good. In retrospect, it would seem that one should also be able to pop the PROM out of the machine and send that in; however, I don't know that this would be an acceptable alternative to Atari. -Charles Green -- {decuac.dec.com,cucstud,sundc}!c3pe!charles ex::!echo Boo:
